Spiders have always lived alongside humans, so it’s surprising how much we still don’t know about them. One long-standing mystery was related to how spiders detect smells. Now, our latest research has finally uncovered the secret.

In a study published in Proceedings of the National Academy of Sciences, we demonstrated that male spiders use olfactory hairs called wall-pore sensilla on their legs as a “nose” to detect the sex pheromones released by female spiders.
